go-cryptonote-pool

High performance CryptoNote mining stratum written in Golang.

Stratum feature list:

• Concurrent shares processing, each connection is handled in a lightweight thread of execution
• AES-NI enabled share validation code with fallback to slow implementation provided by linking with Monero libraries
• Integrated NewRelic performance monitoring plugin

Installation

Dependencies:

• go-1.6
• Everything required to build bitmonero

Install required packages:

go get github.com/yvasiyarov/gorelic

Mac OS X

Download and compile Monero daemon.

Now clone stratum repo and compile it:

git clone https://github.com/sammy007/go-cryptonote-pool.git
cmake .
make

Notice that for share validation stratum requires bitmonero source tree where .a libs already compiled. By default stratum will use ../bitmonero directory. You can override this behaviour by passing MONERO_DIR env variable:

MONERO_DIR=/path/to/bitmonero cmake .
make

Linux

Installation on linux is similar to OS X installation and currently the only dfference is that you should copy .so libs from hashing and cnutil directories to /usr/local/lib or similar dir in order to make CGO happy. I would recommend you to use Ubuntu 14.04 LTS.

In order to successfully link with bitmonero libs, recompile bitmonero with:

CXXFLAGS="-fPIC" CFLAGS="-fPIC" make release

Build CGO extensions:

MONERO_DIR=/opt/src/bitmonero cmake .
make

Build stratum:

GOPATH=/path/to/go go build -o pool main.go

More info on GOPATH you can find in a wiki.

Configuration

Configuration is self-describing, just copy config.example.json to config.json and run stratum with path to config file as 1st argument. There is default XMR address of monero core team in config example and open monero rpc node from moneroclub.com.

Private Pool Guidelines

For personal private pool you can use DigitalOcean droplet. With recent blockchain-db merged into Monero it's ok to run it even on 5 USD plan. You will receive 10 USD free credit there.

TODO

Still in early stage, despite that I am using it for private setups, stratum requires a lot of stability tests. Please run it with -race flag with GORACE="log_path=/path/to/race.log" in private setup and send contents of this file to me if you are "lucky" and found race. It will make stratum ~20x slower, but it does not hit performance if you are soloing with a dozen of GPUs. Look at -debug.fish script for example.

Cool stuff will be added after excessive testing, I always have ideas for improvement and new features.
